J. D. WEAVER, OF PENFIELD, NEW YORK.

IMPROVEMENT IN WHIFFLETREES.

To all whom it may concern:

Be it known that I, J. D. l/VEAVER, of Pen- 'eld, in the county ofMonroe and :State of New York, have invented a new and usefulWhiffle'tree for Plowing or Cultivating in Nurseries or Orchards; and Ido hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,making a part of this specification, in which- Figure l is a bottom viewof the invention.. Fig. 2 shows the rear side of the whifflet-reeinverted.

Similar letters of reference indicate corresponding parts in bothfigures.

The nature of this invention will be clearly understood by reference'tothe drawings and speciration. Y

B in the drawings represents a single Whifetree, which may be madesomewhat less than the usual length. It is provided with a guard 0rclasp, j', projecting from the rear side, near each end. he end of thetugs g being put through these clasps before being attached to the hooksa secures their perfect adjustment. 'Ihe clasps f should be placed farenough from the ends to prevent their striking the tree as thewhiffletree passes it. The hooks a should be so arranged as to causethat portion of the cockeye h which is coupled to the tug g to ll theclasp fvertically, thus securing the proper adjustment ofthe tugs at alltimes.

In cultivating orchards or nurseries it has always been found impossibleto plow either with a single or double team as close t0 the trees as isdesirable with whiftletrees as ordinarily constructed, without greatinjury to them bybruising and knocking oft' the bark..

Even when the greatest precaution is exercised some trees will receivefatal injury in this way. To avoid this I had previous to producing thisinvention4 padded the ends of the whiffletrees and the cockeyes; but thegreat objection to that plan was not only the trouble of applying andremoving the pads every time the team was attached or d etached, butalso their liability to get torn loose and lost off; but thesedificulties are all fully met in the construction ofthe Whittletree andthe manner of connect-ing the tugs herein described. The latter, actingas a sort of fender or pad, has proved entirely efficient in preventingthe end of the whiftletree from barking or even rossing the trees.

These Whiffletrees are perfectly adapted to general use, as well as toplowing and cultivating.

What I claim as my invention, and desire to secure bv Letters Patent,is-

The construction of whiftletrees and the attachment of the tugs gthereto, substantially in the manner and for the purposes herein setforth.
